TEMPEEATURE RECOMMENDED. 



265 



It is now to Java and to India that our attention 

 must be directed in order to procure accurate 

 information on these points. It is there that 

 experiments may successfully be tried, where 

 Chinese acquainted with the art, though not per- 

 haps with the best methods, may be called to aid 

 these researches. Neither at one settlement nor the 

 other, nor at Rio de Janeiro, have the best methods 

 of preparing the green teas yet been introduced. 

 It has been already stated that the roasting vessel 

 used for Hyson tea seems unknown at Java. 



If I may be allowed to offer a conjecture (for it 

 is nothing better), in the absence of more perfect 

 information, regarding the heat desirable to employ 

 in the process of drying black and green tea, I 

 should suggest the under-mentioned temperatures 

 to be tried. 



For the drying of black tea in the 

 drying tube (Poet/ lone/).
